The Colorado School for the Deaf and Blind (CSDB) is a K-12 residential school, located on Knob Hill, one mile (1.6 km) east of downtown Colorado Springs, Colorado, near the famous laboratory of Nikola Tesla. The school was founded in 1874 as The Colorado Institute for the Education of Mutes by Jonathan R. Kennedy, who had previously been steward at the Kansas School for the Deaf. The school began in a rented house in downtown Colorado Springs with seven students, three of whom were Kennedy's own children. One of his children, Emma, later married Frank H. Chaney, who was also Deaf, and they became the parents of the actor Lon Chaney.
